The Guardian recently ran a piece by a group of economists, one of them a Nobel laureate, arguing that economic growth is a doomed strategy. I went and looked at what this movement actually publishes, and I fell into a rabbit hole I did not expect. I think these people are dangerous. Let's take a look.

A physicist proposes that quantum uncertainty affects the entire universe: we cannot both know how large the universe is and how fast it is expanding

In 1983 Benjamin Libet found that brain activity predicts your movements before you are aware of deciding to move. The result has been reproduced many times, and it has been used ever since to argue that free will is an illusion. Three new papers say the measurements were fine but the interpretation was not. Let's take a look.

I looked at the reports about the OpenAI/Huggingface incident and I think we're not talking enough about the most worrisome part

The butterfly effect is much stranger than most people think, and the famous line about a butterfly in Brazil isn't what Lorenz actually meant. A group of researchers has now worked out that quantum physics puts a hard wall on weather prediction, at 129 days. Not difficult after that. Impossible. And this has implications far beyond the weather forecast because chaos enters in everything from nuclear fusion to robotics to black hole physics. Let's take a look.

The dark matter search LUX-ZEPLIN has announced that they have made a detection that could be the first ever evidence for a dark matter particle. Just what have they measured, what could it be, and what does it mean? I have a brief summary.

Artificial intelligence has eaten mathematics. In the past few months alone it turned up a counterexample to a conjecture open since 1939, disproved a thirty-year-old result, and made real progress on the Riemann hypothesis. Young mathematicians are somewhere between depression and anger about it. Physics is next, and almost nobody is talking about it. Let's take a look.

An astrophysicist has claimed that some unidentified anomalous phenomena that were observed in recent years in the United States might be warp drives. He has written a paper about it in which he calculates how such a warp drive would look. I have a brief summary.
